4 Claims.

An object of the invention is to provide a cleaning device which shallbe simple and inexpensive in construction and simple in operation.

Other objects and advantages reside in certain novel features ofconstruction, arrangement and combination of parts, which will behereinafter more fully described and pointed out in the appended claims.

In the annexed drawing given by way of example, and in which likereference characters indicate corresponding parts throughout the severalviews:

Figure 1 is a side elevational view of the assembled device.

Figure 2 is substantially a longitudinal sectional view of the device.

Figure 3 is a bottom View of same.

Figure 4 is a transverse sectional View of the device.

In the said drawing I is a wood handle provided with indentations I8 andI9, adapted to receive the fingers and thumb of a user While in use, sothat the device will not slip out of the hand. The handle is providedwith saw cuts 22 and 23 that extend the entire length of the handle, andare provided to receive the perforated plate II that is held inassembled relation with the handle by means of nails 24, or othersuitable fastening means.

The bottom plate II is provided with aligned The integral portion I4'the handle I0, and is provided to close one end of the chamber 2l thatis provided above foraminous vulcanite, Celluloid or other heatsusceptive material that may constitute the plate II. The removableblock IB that closes the other end of the chamber is held in place bythe keeper I'I. The block I6 is removed to release the dust from thechamber 2|. The bottom plate is provided with a multiplicity ofperforations 20 that lead into the chamber ZI. It will be noted that theplate I I is curved from side to side as well as longitudinally.

The operation of the device is as follows:

The cleaning device is rubbed quickly back and forth over the pile ornap of a rug or upholstery.

The frictional contact of the cleaning device with the article beingcleaned, imparts heat to the device, which in turn imparts heat to theair in the chamber and expands it, its density is lessened and hence itis pushed upward by colder adjacent portions, which take their placeonly in turn to be driven away. The currents of warmer air flow awayfrom the source of heat, and other currents of colder portions flowtoward it. The

perforations introduce a relatively high resistance between the articlebeing cleaned and the device and imparts a whisk to the pile or nap thusloosening up the dust particles having small kinetic energy. The plateis also negatively electried by the friction, and the negativeelectricity also assists in removing the dust particles.

Other applications and other modifications are contemplated within thescope of the present invention as will be apparent to those skilled inthe art. It is therefore to be understood that the embodiment hereindisclosed is to be regarded as illustrative of the invention and notrestrictive, and the appended claims are to be construed broadly exceptas limitations may be necessary in view of the prior art.

Having described my invention what I claim as new, and desire to secureby Letters Patent is:

1. A device of the class described comprising a handle, a perforatedplate mounted therein and forming therewith a chamber, and means forclosing the ends of the said chamber supporting the ends of theperforated plate, one of the said means being bodily removable as asingle unit so that the chamber may be cleaned.

2. A device of the class described comprising a handle, a perforatedplate associated with the handle and forming therewith an air chamberand having a curved outer surface, the curvature i of said surface beingsuch that it is concave longitudinally of the handle and convextransversely of the handle, and removable means closing one end of thechamber, the other end of the chamber being closed with a xed means.

3. A device of the class described comprising a handle, a perforatedplate having aligned outer surfaces and also having a curved outersurface, the curvature of said surface `being such that it is concavelongitudinally of the handle and convex transversely of the handle, theaforesaid curved surface coalescing with the aligned surfaces, theaforesaid perforated plate forming With the handle an air chamber,members for closing the ends of the air chamber, one of the aforesaidmembers being removable, a keeper for maintaining the said removablemember, the other of the said members being fixed.

4. A device of the class described comprising a handle, a foraminousheat susceptive plate associated with the handle and forming therewithan air chamber and having a curved outer surface, the curvature of thesurface being such that it is concave longitudinally of the handle andconvex transversely of the handle, means for closing the ends of the airchamber, one of the said ends being removable.
